Abstract:
A method of forming a polycrystalline diamond body includes mixing a sintering agent with diamond powder to form a premixed layer, the sintering agent including at least one alkaline earth metal carbonate; forming an infiltration layer adjacent to the premixed layer, the infiltration layer including an infiltrant material including at least one alkaline earth metal carbonate; and subjecting the premixed layer and the infiltration layer to high pressure high temperature conditions.
